A) x + y = -7
B) x * y = 3
y = 3/x then put this into equation A
x + 3/x = -7
x^2 + 3 = -7x
x^2 +7x + 3 = 0
x = -6.5414 and x = -0.45862

It's because a tenth means that you've divided it by 10. So if it's 20, it means you're multiplying tenths by 20, leaving you with 2 wholes.

For example, you have 2 cakes and you cut each into 10 slices, the slices are each one tenth of the whole cake, and in total there are 20 tenths.
